<DIV><FONT face=Arial size=2>George I agree with your comments with one
exception. The Sullivan controll line kevlar is the best of all worlds for our
hookups. There is no stretch, no weight, no electromagnetic problems. It is
unidirectional with, probably, a low COE like carbon.</FONT></DIV>

<DIV><FONT face=Arial size=2>Sorry Guys, I have some thoughts and opinions on
this that are based upon my own logic, however flawed,and which may or may not
coincide with someone else's logic.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Anytime you have a control system that is based
on a system that incorporates an oscillatory motion (fore/aft up/dn) the
ultimate result of this motion will generate wear somewhere within the system
and wear translates to slop.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I think my contention would be that Lance had it
right in the first place and was ill-advised by some well intentioned
souls who may have had what they assumed to be good results, but failed
to base their conclusions on really long-term experience(who really knows for
sure?)</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I have long felt that pull-pull cables
(vinyl-coated steel) present the most reliable connection for the
elevator and rudder inputs.They do not require that the horns
be expensive ball-bearing units, they are the lightest by far and due to
the fact that they are always under tension the generated wear manifests
itself against only one wear surface instead of the two in the push-pull
set-up. If the installation can be modified in such a way that the servo can
be mounted just ahead of the stab the COE of the fuse can be rendered
virtually inaffective. </FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>With time, you may experience some slight
lessening in cable tension (very slight) which can quickly be rectified by
disconnecting the clevis and spinning the eye a half turn at each
connection.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>I have used Kevlar thread and continue to do so,
but not on two-meter projects.Kevlar stretches for quite a period of time
before settling to it's final length.</FONT></DIV>

<DIV><FONT face=Arial size=2>This rots. I've used pull pull forever
and switched to the deps system due to heavy promotion by Mike Harrison and
Bryan Hebert. They say it will be more precise. Can anyone
corroborate this? I'd hate to switch to a system that has more
downside than upside.</FONT></DIV>
